Re: 1st previous node()

Re:  1st previous node()
Yes, but preceding incorrectly would consider the children of the
previous node, so preceding-sibling::*[1] is the right answer, and
then of course ../*[1] would select the first ancestor.  I'll give
this a go.

Hopefully someone can chime in on the generate-id issue I am having,
I'm really expecting a consistent answer so assuming I might be doing
something wrong.

Karl..
